IMPROVEMENT IN GRATES FOR FIRE-PLACES, STOVES, AND FURNACES.

Specification forming part of Letters Patent No. 153,087, dated July 14, 1874; application filed May 26, 1873. i

To all whom it may concern:

Be it known that I, JOHN A. KERNOCHAN, of Pittsfield, Berkshire county, State of Massachusetts, have invented an Improved Gonstruction of Grates for Fire-Places, Stoves, and Furnaces, of which the following is a specification:

This inventionhas relation to forming so many of the bars of a grate hollow as will afford a connected passage for the flow ot' illuminatinggas to points distributed in the grate, where jets of flame can be brought in contact with the fuel contained in the grate to ignite the same; and in providing the hollow grate with a suitable connection for a supply-pipe at a convenient point thereon, which supplypipe for the gas maybe permanently attached to the grate, with a cock to out off the flow of gas when the fire is lighted or may be a flexible tube, to be withdrawn from a nozzle upon the grate at the proper time; the object of the invention being to enable the gas in general use for illuminating purposes to be utilized for the purpose of kindling wood or coal fires, by being conducted from the burner, or carried by a special pipe, through the grate, to.

several points of contact with the wood or coal to be lighted, and to thereby save the expense, trouble, and uncertainty attending the employment of ordinary kindling materials.

In the drawin gs,1*igure I shows a side view of a fire-place with my improved grate. Fig. II shows a plan view of the grate; and Fig. III a section of one bar with a burner.

G is the grate, having the cross-bars g g g g and the front bar H hollow, bar H establishing a connected passage between the bars g g g g, and permitting the rear bar B to be solid. Upon the center of bar H, as a convenient point, I place a nozzle, h, upon which to secure the end of a flexible supply-pipe, M, as seen in Fig. 1, which can be readily detached when the fire is kindled. At various points upon bars 1 g g g are arranged as many small burners b b b, &c., as is required to supply flame to all of the fuel above the grate, though simple apertures would serve the purpose of admitting the escape of gas in flame; but in practice 1 insert small burners, substantially as shown in Fig. III, that may readily be removed to be cleaned, and that will, while allowing the flame to reach the fuel, shield the orifice through which the gas flows from the contact of the fuel above which might fill it or clog it.

A grate on my principle may be readily adapted to all stoves, furnaces, open grate fire-places, or Franklin stoves; and is readily made to be detached for the purpose of being cleaned, should occasion demand it.

Now, having described my invention, what I claim is A fire-grate composed of the solid rear bar B, hollow cross-bars g, with burners b, and the hollow front barH with nozzle h, substantially as and for the purpose set forth.
